Control of Anthracnose Disease in Swietenia macrophylla using Trichoderma virideas Biocontrol Agent

Abstract:
The biocontrol potential of Trichoderma viride against anthracnose pathogen Colletotrichum alienum was studied in vitro and under greenhouse conditions. In vitro antagonism test carried out between T. viride and C. alienum showed a radial growth inhibition of the pathogen by 75% at 35°C. The greenhouse studies involved inoculation of healthy Swietenia macrophylla seedlings with suspensions of T. viride and fungicide (Carbendiazim) followed by addition of the pathogen, C. alienum inoculum after three days. After inoculation the infected leaf area was measured weekly and Area under the Disease Progress Curve (AUDPC) was calculated and compared among the treatments. The results showed that T. viride (AUDPC = 120) and fungicide (AUDPC = 93) significantly (p<0.05) reduced the disease compared to the untreated control (AUDPC = 1200). T. viride significantly controlled the pathogen on par with fungicide treatment. This study revealed that the application of T. viride has good potential in controlling the anthracnose disease of S. macrophylla.
